32 The second calculation was to get the average point or average percentage of
each English LKS in fulfilling each requirement. The researcher used the same formula as the previous one. There were only some exceptional.
The second formula:
=
x 100
= Arithmetic mean xn
= total percentage of each LKS chapter in fulfilling each criterion n
= total number of the criterion on each requirement The third calculation process was used to find the total percentage of each
LKS in fulfilling all three requirements. The researcher put different weight on each requirement. Didactic requirement distributes 25 of the percentage. The average
percentage of each LKS in fulfilling didactic requirement was multiplied by 25. Construction requirement distributes 50 of the percentage. The average percentage
of each LKS was multiplied by 50. Technical requirement distributes 25 of the percentage. The average percentage of each LKS in fulfilling technical requirement
was multiplied by 25. In order to find the total percentage of each LKS in fulfilling all three requirements, the researcher added all three percentages of each LKS.
33 In order to categorize the result of the calculation, the researcher divides the
result into four categories based on the percentage. The four percentage divisions are shown below:

Categorization
76-100 Good
51-75 Fair
26-50 Sufficient
0-25 Bad
F. Research Procedures
In conducting the research, the researcher did several steps such as deciding the topic of the research, collecting the data, formulating the problem formulation,
analyzing the data using the appropriate instrument, and writing down the report.
1. Deciding the topic of the research The first step taken by the researcher in conducting this study was by deciding
the topic of the study. There were several reasons why the researcher took this topic. First, the researcher felt it was the researcher
’s responsibility to take a part in developing world of education. The researcher also realized that books were used as
the main media in the process of teaching and learning in class. It is what makes the quality of the media should be considered carefully. A good quality book gives
34 contribution to the successful learning. That was one of the reason of why the
researcher took initiative to learn more about the quality of those three LKS.
2. Collecting the data Collecting the data is one of the most consuming time parts which are done by
the writer in doing this research. It is because of the writer should choose the data carefully. The data which are gathered by the writer should be relevant to the study.
One of the obstacles in gathering the data is that the writer has to choose the trusted source.
Gathering all the data about the previous study which had done by some researcher before is also a time consuming step. All the data from the previous
researchers which had done similar study really help the writer in order to find more idea about what should be done.
3. Formulating problem formulation The third step in doing this research is finding the problem formulation.
Finding the problem formulation is a very important step. It is because of by knowing the problem, the next step is that the researcher focuses on what will be caused by the
problem that exists. This problem later becomes one of the matters that are going to be solved in this research.
In this research the writer focuses on the question whether the LKS which are used in vocational high school has fulfilled the didactic requirement, construction
35 requirement, and the technique requirement or not. LKS is one of the media that used
intensively in the process of teaching and learning in class. One reason is because of the total amount of the exercises in it that may help the students to have more practice
time. Realizing that those three aspects are very important consideration in making LKS, the writer tries to seek the answer.
4. Analyzing the data Analyzing the data is on the next line of the research after finish gathering the
data needed. After considering several things the researcher chose to use the three criteria to be used such as the didactic requirement, the construction requirement, and
the last one is the technical requirement. Those three requirements become the tools to measure the level of the LKS.
Three criteria which have to be considered in the making of LKS are didactic requirement, construction requirement, and the last one is the technical requirement.
Every criterion consists of some more detail point. The total amount of the point for every requirement is varied one another.
There are three tables which contain some points which have to be fulfilled by those three LKS. First table consists of some points which have to be fulfilled by
those three LKS related to didactic requirements. The second table, it is consisted of some points which are related to the construction requirements. The third table, it
consisted of some points which are related to the technical requirements.
36 Having all those points for every criterion, it helps the writer in analyzing the
LKS in detail. Every point which is fulfilled by the LKS will get one point. On the other hand, the criterion which is not fulfilled by the LKS gets no point at all. The
result of the analysis is in the form of percentage.
5. Writing the report Writing the report becomes the last step in doing this research. It can be done
when the writer has done the four steps above. The result of the research which is done by the writer is in form of thesis.

CHAPTER IV RESEARCH RESULTS AND DISCUSSION
This chapter contains of four main parts. The research result and findings are divided into four main parts which answer the question about the fulfillment of those
three LKS on the didactic requirements, construction requirements, technical requirements, and the total percentage of each LKS Formatif in fulfilling the three
requirements.
A. The Fulfillment of Didactic Requirement
The didactic requirement consisted of six points which became consideration whether the LKS formatif could be categorized based on the achievement in fulfilling
the requirement. The researcher analyzed the LKS formatif per chapter. Each LKS formatif was analyzed per chapter in order to get more detail information and data. In
the process of analyzing, the researcher found that there were some criteria that could be fulfilled by certain chapter and there were some criteria which could not. The
achievement of each chapter is as seen below. It worked under this condition, every chapter which fulfilled the criterion was given score 1. Every chapter which did not
fulfilled the criterion was given score 0.
